New delhi-based roop telsonic ultrasonix limited supplies uultrasonic-welding system is offered by new delhi-based roop telsonic ultrasonix limited. In ultrasonic welding systemin which thermoplastic components are held under pressure and are applied with ultrasonic vibrations. Following are some technical features of this ultrasonic welding system which include: the heat generated at interface of components, melts the materials, which fuses together to give solid bond.As heating is selective through introduction of specially designed low contact surface area called energy director, there is hardly any distortion and degradation of component. Ultrasonic energy is applied, ddepending on material, size, shape of component to be welded, ultrasonic energy is applied. Apart from joining of two thermoplastic injection-moulded components, this technique finds its applications incan also be used for forming, spot welding, riveting, metal insertion in plastics, slitting of non-woven thermoplastic fabrics and sealing of laminated foils. Very high frequency electrical energy [20 or 36 khz] is generated by thethe generator of system generates very high frequency electrical energy [20 or 36 khz], which is transformed into mechanical vibrations of same frequency by converter. As various materials/applications require different amplitudes of this vibration, a mechanical amplifier called booster and is used to increase the amplitude this booster is used. The horn is the tool, which finally impart these vibrations in the component, and is designed to suit the component size and configuration. Converter, booster, horn assembly are held together in pneumatic press. As normally the welding time is less than a second in most of the operations, high production with consistent quality and strength is achieved.The precise time setting with least count of 0.001 seconds, avoids over welding, deformation, reduction in production rate and excess consumption of power. Microprocessor of system helps in calibration and quality control and acts as faultfinding tool allowing operator to rectify the system. Easy capacity up gradation, is allowed by mmodular design of system allows easy capacity up gradation. Built-in electronic amplitude setting allows the user to choose amplitudes through generator, between 70 and 100 percent without changing the booster. Precise setting of energy is allowed by energy mode option in addition to time mode allows precise setting of energy as per job requirement. Welded box structure pneumatic press gives hhigh rigidity in all axes is provided by welded box structure pneumatic press . Use of mps-2 will give additional features of force triggering and limits for acceptance/rejection. This ultrasonic welding system is useful in automobile filters, floats, batteries, clutch cables, pump housing and impellers, electrical switches and switchgears, connectors and steam iron jackets.
